BURNER.

Application filed. February 8, 1923.

This invention relates to burners for gas, preferably acetylene, and While it is adapted or designed particularly for use in a flat iron, it may be employed for other purposes where a burner olf this design can be used.

The object ol my invention is to provide improved 'means ior liiixing the gas and air and preventing the objectionable alarming popping sound which frequently 'tollows the sl'iutting oil ol the gas. i

i iurther object is to provide improved means for connecting the burner with the base oi' theiron topreveiit the accidental Withdrawal of the burner troni the iron and the danger' or' lire resulting from such withdrawal by a child orsome person unfamiliar with devices ol" this kind.

rlihe invention consists generally in various constructions and combinations all as hereinafter described and particularly pointed out in the claims.

in the accompanying drawings 'forming part olf this specification Figure l. is an outside view oi a burner eiulgiodying my invention;

Figure 2 is a vlongitudinal sectional view of the same;

Figure 3 is a side view partially in section oi a flat iron showing my invention applied thereto;

Figure lis a sectional view on the line i-4 olf Figure 2;

Figure 5 is a sectional View on the line 5 5 of Figure 2;

Figure G is a sectional view on the line (3-6 of Figure 2;

lFigure 7 is a detail View of a portion of the burner.

ln the drawing, 2 represents the burner head having a tapered end 3 provided Withan orifice l. The head is in the 'form of a shell interiorly threaded at one end to receive an exteriorly threaded plug 5 formed on a shank 6 in which a gas passage 7 is provided leading to the interior of the head 2. ir intake ports 8 are provided in the wall ol the shank and a gas tip 9 is mounted `in the shanlr and communicates through a tube 10 with a suitable source oi' supply. fl.. flange 1l is toi-ined at the inner end oi the shank G and provided with a beveled sur'iace 12, and When the head of the burner is thrust into the socket 1B in the base or' the iron le, the flange will contact with the outer wall ot the socket and the beveled surface Serialo. 617,891.

ot the flange Will engage a spring-pressed pin 15, forcing` it outwardly against the Jtension or its spring until the flange hasinoved past the pin whereupon the pin Will spring bachi to its norm al position in the rear or the [lange and loclr the burner firmly in its soclret preventing the Withdrawal thereof until the pin is Withdrawn by grasping the linger grip 16 thereon.

lflithin the head 2, is a removable shell 17, open at each end and provided with flanges 18 and 19, il, plate 2O is seated against the flange 19 and is imperforate except i'or a se* ries ot holes 2l provided therein near its periphery. series ot rings 22 are placed with in the shell 17 and spaced from one another and from the plate 220, each ring having holes therein to register with the holes 2l in the plate 20. At the end of the shell 1 7, a ring 23A is provided that is iinper iforate, thereby closing the direct passage 'through the holes iii the other rings, said ring and the perforated rings being` held iu place by the llange 18 and all of them ben ing spaced apart as described.

The central passage 24 through the rings communicates with the passage 7 and is closed at its inner end by the plate 2O so that gas flowing through the passage 7 can not pass directly through the shell but must flow utwardly at right angles thereto between the perforated rings and into the holes therein, and thence through the holes 21 in the plate 2O to the tapered end of the burner head and the orifice 4. In this Way, the gas is compelled to follow a tortuous path and is so broken up and mixed with the air that there is no possibility of backfire or popping` in the burner when the gas is shut oil?.

The gas mixer, it Will be noted, has a plurality oi narrow radial gaps through Which the is delivered to the ports leading to the burner tip. The number oit these gaps Will vary, ot course, with the desired capacity o the burner, more rings being` used and more gaps provided when it is desired to pass a larger volume or' gas to the tip. lVhenever desired, the shank member 6 may be removed and then access easily had to the mixer for cleaning or other purposes.

claim as my invention 1. A gas burner comprisinga shell having a tip and discharge orice therein, a sleeve litting within said shell, a disc arranged within said sleeve and having a closed cengrs tral portion and pertorations encircling said central portion, a plurality of rings also fitting Within said sleeve and spa-ced apart, and having holes to register with each other and with the holes in said disc, the outer ring of the series having no pertorations therein, means having a gas passage communicating with said sleeve and rings, the gas flowing outwardly between said rings and passing through the holes therein to said tip.

2. A gas burner comprising a tip having a discharge orifice, a series of rings fitting Within said tip and spaced apart, each ring being provided With a series ot pertorations adapted to register with the corresponding pertorations of the other rings, a ring having no pertorat-ions therein at one end of said group, a disc at the opposite end of said group having pertorations to register with those in said rings, said disc closing the direct passage through said rings and compelling the gas to flow outwardly between said rings to the pertorations therein.

3. ik gas burner comprising a shell having a tip and discharge oritice therein. a gas mixer itting Within said shell and having a central passage that is closed at the end adliacent said tip, the Walls of said passage having a series of narrow gaps radiating from said passage and said mixer having ports leading to said tip and communicating with said gaps.

et. A gas burner comprising a shell having a tip and discharge orilicetherein, a gas mixer itting Within said shell, and comprising a sleeve having a passage open at one end and closed at the other, the Walls of said passage having a series of narrow gaps radiating therefrom, and also4 having a series of ports communicating with said gaps and leading to said tip.

5. A gas burner comprising a shell having a tip and discharge oritice therein, a gas mixer itting Within said shell and comprising a sleeve, a series of rings fitting Within said sleeve and spaced apart to form radiating gaps between them, cans for |closing the central opening through said rings and sleeve adjacentl said tip, and said rings having ports communicating with said tip and with said gaps.

6. ln a gas burner, a mixer comprising a sleeve, a disc itting Within said sleeve and having an impert'orate central portion and perforated near its periphery, a series ot rings fitting Within said sleeve and spaced apart to form gaps between them. and having ports for communication With the perfor-ations in said disc and With said gaps, and means Within said sleeve for closing the ports in said ring remote from said disc.

7. burner comprising a shell having a tip and discharge ori tice therein, a gas mixer fitting Within said shell and provided with a series of radially extending gaps and gas ports communicating with said gaps and with said tip, and a plug fitting Within said shell and when removed permitting the removal of said mixer.

In Witness whereof, I have hereunto set my hand this 3rd day or" February, 1923.
